Over the years, I have cellared a variety of Barley Wines, including Sierra Nevada's Bigfoot Ale. I cracked open a couple of bottles of their year 2000 effort and I'm happy to say that after 10 years in the bottle, it is a great brew! It definitely has matured very well in the bottle. Very flavorful, malty and smooth. No hop flavor/aroma to speak of. Very nice. This brew doesn't need any "drink by" date IMO.
